Title (EN) WELDING METHOD AND JOINING MEMBER
(FR) PROCÉDÉ DE SOUDURE ET ÉLÉMENT D'ASSEMBLAGE
(JA) 溶接方法および接合部材
Abstract:
(EN) The present invention realizes a welding method with which it is possible to manufacture a joining member having superior toughness. The welding method includes: a first heat-inputting step for forming a joined section in which ferrite-based single-phase stainless steels are joined with each other by inputting heat from a first heat source; and a second heat-inputting step for inputting heat to the joined section from a second heat source so that the cooling speed of the joined section reaches 500ºC/s. or less while the temperature of the joined section is in a range of 1300ºC to 700ºC after the first heat-inputting step and before the temperature of the joined section decreases to 700ºC.
(FR) La présente invention réalise un procédé de soudage avec lequel il est possible de fabriquer un élément d'assemblage ayant une ténacité supérieure. Le procédé de soudage comprend: une première étape d'apport de chaleur pour former une section assemblée dans laquelle des aciers inoxydables à phase unique à base de ferrite sont joints les uns aux autres par apport de chaleur provenant d'une première source de chaleur; et une seconde étape d'apport de chaleur pour apporter de la chaleur à la section assemblée à partir d'une seconde source de chaleur de telle sorte que la vitesse de refroidissement de la section assemblée atteint 500°C/s ou moins tandis que la température de la section assemblée est dans une plage de 1300°C à 700°C après la première étape d'apport de chaleur et avant que la température de la section assemblée diminue jusqu'à 700°C.
(JA) 靱性に優れた接合部材を製造することができる溶接方法を実現する。第1の熱源によって入熱することによりフェライト系単相ステンレスどうしを接合した接合部を形成する第1入熱工程と、第1入熱工程後に前記接合部の温度が700℃まで冷却される前に、前記接合部の温度が1300℃~700℃の温度範囲において、前記接合部の冷却速度が500℃/s以下となるように第2の熱源により当該接合部に対して入熱を行う第2入熱工程と、を含む
